Timepiece

ABSTRACT

A timepiece, comprising indicating means driven by a movement for indicating the hours and minutes and also the date, characterized in that there are disposed around the said indicating means a first annular surface carrying indications of the dates of a month of 31 days, and a second annular surface concentric with the first one and carrying indications of the consecutive days of the week of at least five consecutive weeks, at least one of said annular surfaces being disposed on a turning ring which can be rotated manually for radially aligning the indications of the dates and the indications of the days of the week to form a complete calendar of a month.

Embodiments of the timepiece according to the invention will bedescribed hereinafter, by way of examples, with reference to theaccompanying drawing in which:

FIG. 1 is a plan view of a watch and FIG. 2 is a diagrammatic sectionalview of the watch.

The watch shown in the drawing includes, in known manner, means forindicating the hours and the minutes in the form of hands 11 and 12.These hands, which cooperate with time markings on a dial 13, are drivenby a conventional movement (not shown) housed in a compartment 14 of awatch casing, which movement also drives a date ring mounted below thedial. One of the date indications on this date ring is visible in awindow 15 in the dial 13. The elements described hereinbefore arearranged in a housing comprising a case middle part 16 and a crystal 17.

In the case middle part are also mounted a stationary bezel 18, a firstturning bezel l9 and a second turning bezel 20. The visible annularsurface of the stationary bezel 18 carries 37 indications of consecutivedays of the week. The first turning bezel 19 is arranged inside thestationary bezel l8 and has an annular surface which is concentric withthe annular surface of the bezel 18 and carries indication of the datesof a month of 31 days. Each one of these date indications on the bezel19 is in radial alignment with one of the indications of days of theweek provided on the stationary bezel 18 so as to form a completecalendar of one month. Since different months do not begin with the sameday of the week the bezel 19 can be turned manually at the end of everymonth for aligning the first day of the succeeding month with thecorrect day of the week. For this purpose it would be sufficient, inprinciple, if the bezel 18 carried, in an uninterrupted series,indications of the days of the week of five weeks. In the watch shown inthe drawing the stationary bezel 18 is interrupted by a window 21, andtherefore 37 indications of days of the week must be provided.

The second turning bezel 20 is mounted below the stationary bezel 18 andcarries indications of the 12 months of the year. One of theseindications is visible in the window 21 of the stationary bezel 18. Atthe end of every month the bezel 20 can be turned manually for makingthe indication of the next month appear in the window 21.

As the turning bezels l9 and 20 are mounted inside the case middle part16 and below the crystal 17, two

crowns 22 and 23 carrying pinions are provided for rotating the bezels,the pinions being in engagement with teeth formed on the bottom surfaceof the bezels 19 and 20. Only the pinion 24 associated with the crown 23is visible in the drawing in FIG. 2.

It is obvious that the bezel 19 carrying the date indications could bereplaced by a turning bezel mounted on the outside of the case middlepart 16, and outside the crystal, so as to be capable of being manuallyrotated directly by the fingers. The bezel 20 carrying the monthindications could be omitted, and the indications of the days of theweek could then be carried directly on an annular surface of the dial,instead of on a stationary bezel.

The indications of the dates and the indications of the days of the weekcould also be interchanged, i.e., one could dispose the date indicationson a stationary annular surface and the day of the week indications on aturning bezel. The surfaces carrying the two kinds of indications couldboth be turning, but in any case it is necessary that they can also berotated relatively to one another.

The watch described above shows, in addition to the time and the date,also a complete calendar of the instant month and an indication of thename of this month, requiring only a simple manual setting once in everymonth. If desired, one could also provide means driven by the movementfor indicating in known manner the day of the week in the window 15 ofthe dial, but it will be appreciated that this is in generalsuperfluous.

What is claimed is:

1. A timepiece, comprising indicating means driven by a movement, saidindicating means including hands for indicating the hours and minutesand a date ring for indicating the date, characterized in that there aredisposed around the said indicating means within the casing of thetimepiece a first annular surface carrying indications of the dates of amonth of 31 days, a second annular surface concentric with the first oneand carrying indications of the consecutive days of the week of at leastfive consecutive weeks, at least one of said annular surfaces beingstationary and having window formed therein, the other of said annularsurfaces being disposed on a turning ring which can be rotated manuallyfor radially aligning the indications of the dates and the indicationsof the days of the week, and a third annular surface carryingindications of the 12 months of the year, said third annular surfacebeing disposed on a turning ring which can be manually rotated forpresenting one of the twelve month indicationsin the window of said atleast one stationary annular surface, said surfaces cooperating to forma complete calendar of a month.

2. A timepiece according to claim 1, characterized in that the saidturning rings are arranged inside the casing of the timepiece, and areprovided with teeth, and in that a separate crown carrying a pinion inengagement with said teeth is provided for rotating each of the rings.
